Good evening everyone.
I am creating this thread because latelly I had an idea for an app (ipad and iphone for now) directed to betta fish owners.
It would be a virtual betta fish that could be controled by the owner or wander around the screen randomly, the idea would be to put the screen close to the tank so the real betta would interact with it.
I already created a prototype which is basically a 3d model of a betta fish on screen and I was able to test it on my little betta. He reacted just like looking at the mirror! I also tried with a model looking more like a female Betta and he got very agitated, even more than with the male one.

My main question: Is this harmful to the fish? Because I would not want to make an app that does any harm to the fish.
Second, could this app be useful somehow for betta owners or even breeders? Would someone have interest in it?
Thanks in advance for the valuable feedback.
